AB: We present a community-based, coarse resolution fault model (CFM) of southern California. The model has undergone specification, design and implementation stages all of which had a large degree of input from the community provided with the Southern Californian Earthquake Center and in particular the CFM working group. Here, we deliver the first complete CFM to the user community and describe how to access the model database. The model consists of ca. 120 faults some of which have alternative representations based on contrasting geologic interpretations. The geometry of each fault surface is modelled by a triangulated mesh with the node location and connectivity stored in a simple ASCII formatted digital file. Access to these files is provided by WWW. The URL of this resource is http://structure.harvard.edu/cfm. A graphical map interface and search capabilities let users select individual faults or groups of faults. A icon style perspective view and list of attributes suchs as fault sense and slip rate of each selected faults is shown and users can download individual faults or the selection in a single collection. The web resource is driven by a relational database (postgresql) and WWW mapping software (mapserver).
